In the meantime, the National Weather Service advises to take extra precaution while driving, as "roads will increasingly become hazardous."

Most of Illinois is under winter storm warnings and advisories with up to 9 inches of snow forecast for southwestern parts of the state.

The National Weather Service stated that snow was expected to begin around 3 p.m. Friday in southwestern Illinois and spread northeast throughout the evening, reaching the Chicago area by Saturday morning. Snow totals are to taper to the northeast with parts of southwestern Illinois forecast to receive up to 9 inches and the Chicago area expected to get between 2 and 3 inches.

Dry air to the north of the approaching system is expected to cause a sharp cutoff line, where little to no snow will fall, in areas like Lake and McHenry counties.

Though models still vary on the predicted snow totals, an amount over one inch in Chicago would mark the first time the area has seen more than an inch of snow since Nov. 26.
